Last week I discovered a vulnerability to avoid/overrun/bypass the new
protection for Local JS Execution on IE (winxp sp2)
--cut here--
<script>
window.alert("Example Exploit");
</script>
--cut here--
(Copy and paste into your Notepad and save it as EXAMPLE.HTM)
If you open EXAMPLE.HTM, your IE blocks this code and shows a yellow bar over
the webpag.
But I discovered a vulnerability to allow Local JS Code to execute on IE, the
exploit is:
"Go to Control Panel / Display Config and set as the desktop background the
example webpage (EXAMPLE.HTM), once this is done, the code will be executed
without showing any warning in IE"
